Love 3D printing career,but don’t knw how to start?Here are some suggestions

3D printing can seem like a daunting field to get into. After all, while there’s a lot of information, it is not a field that is “newcomer friendly”. The online information can seem very disorganised. Most people posting about the industry will jump to the nitty gritty details. Consequently, this leaves behind a lot of people who shy away from untangling engineering jargon. Another issue is discerning the good advice from the bad. Due to these obstacles, here’s our advice on how to get started. The first way to learn is to take up courses. Admittedly, it’s hard to find local colleges, schools and universities with a sufficient   huge 3D printing  course. Thankfully, there are multiple online providers willing to pick up the slack on this. While the experience won’t be hands-on, it is still valuable nonetheless. For the practical side of it, you can always buy a DIY 3D printer kit and assemble it as you learn. Instructables has an amazing 3D printing class. It’s also geared towards

Hong Kong students set the Guinness World Records for the largest 3D print sculpture

Large 3D  pr inter  are breaking ground everywhere it seems. Their wider applications have reached new levels, from teaching to modeling to art. Students in Hong Kong have used 3D printing for all 3 purposes and broken the world record for largest 3D printed sculpture in the process. 3 students studying in Form Two at Bethel High School printed a sculpture depicting the Hong Kong Harbourfront. The sculpture spans  35 square metres  with  1,214 3D printed individual pieces . The students submitted it as part of the 20th anniversary celebrations of Hong Kong’s return to Chinese rule. 236 entrants took part in the competition, with prizes for the top 4 contenders. How they did itThe students mapped out 20 different landmarks on the harbour from scratch with CAD design software. One of the students remarked that it took them 3 months and 3 different models to arrive at one they were happy with. They were handed the award by Guinness’ World Record representatives. Their entry will be viewab

Researchers at the University of Washington print objects that are connected to the radio

Researchers at the University of Washington have developed a ground-breaking new means of printing objects that are capable of communicating with other devices without the need of electronics. The research details how a toolkit for wireless tech allows the 3D printing of these devices with standard filaments. These devices can contain weight scales, flow sensors and anemometers that can transmit sensor data. As a result, the researchers have opened up the potential of sending signals to wifi receivers with no battery required. This data enables devices to inform the user of changes in weight, air pressure or water flow automatically. The researchers used “Backscatter techniques” to power the communications tech. Backscatter systems use antennae to transmit data by reflecting radio signals emitted by a WiFi router or other device. The devices use a conductive printing filament that mixes plastic with copper as the base for the antenna. The team even borrowed principles

The growing trend of 3D printing toys and what it means for manufacturers

A recent study points out that,  large 3D printing machine   have enabled parents to save anywhere from 40 to 90% on children’s toys. The study also highlights how this trend is cutting down on manufacturer’s profits. Additionally, desktop 3D printers have given prosumers the ability to create a manufacturing hub. As a result, home entrepreneurs are taking a slice of the toy industry, poised to grow to $135 billion by 2020. As of now, there are no certain figures on just how much domestic production can off-set this titanic industry, but cost efficiency is on their side. 3D printed toys can reduce costs by about 90%. Another advantage is the ability to create unique toys that aren’t available on the market. Or perhaps even substitutes for massive branded toys. Perhaps LEGOs are a bit expensive as famous, branded goods tend to be. Parents could instead make their own LEGO knock-off blocks at home, after all, they aren’t remotely complex in shape or size. H

Researchers at University of Nottingham 3D Print Fully Functional Electronic

Printing fully operational parts is one of the most coveted goals in modern additive manufacturing. This is especially true of electronics. While researchers have posited many versions of such a model, it appears a team from University of Nottingham may have made a crucial breakthrough. The researchers have proposed a method of building function electronic circuits using inkjet printing. This exciting new development has the potential for electronics producers to make ready to use components directly. Their method essentially uses  3D printing  to make 2D printed electronics. The circuits are printed with very rapidly using conductive inks and insulating polymer inks. Aside from the clear importance to functional electronics printing, the use of multiple materials also makes this research a leap forward in multi-functional additive manufacturing, a type of printing that involves multiple materials at once. Multi-material Inkjet Printing Professor Chris Tuck, Professor of Materials Eng

Researchers Convert Yellowstone Methane Into 3D Printing Materials

Researchers in the US have found a way to convert methane from geysers into 3D printing materials. In a joint project between Montana State University, South Dakota School of Mines and Technology and the University of Oklahoma, researchers believe they can transform this greenhouse gas using special bacteria called methanotrophs. “What we are intending to do is understand their metabolism better, understand how they form biofilms slime,” said Montana State professor Robin Gerlach. “Once we know how these organisms work we can hopefully assemble them in a way that is most productive.” The researchers hope to utilise the bacteria’s ability to metabolise the gas into biofilm. By arranging the bacteria into a desired shape, they can grow the materials similar to how bioengineers produce artificial tissue. The team is currently working towards a light-reactive version that can be used in SLA printers. This opens up many doors since microbes are very reactive towards light.

3D Printable Design (DFP)

Printing a functional object can be tedious. Experienced users know. There are many caveats to outputting a great print. One of the most effective methodologies for getting good prints is focusing on design. Designing an object specifically for 3D printing will provide better all around results as compared to a design that has not taken 3D printing into consideration. Design for printability (DFP) is a conceptual framework for designing objects for printing. If you are not a designer, this series will promote better judgement in regards to your choice of virtual object and approach to printing. At the very least, you the reader, will walk away with a better understanding of  large 3D printing  in general. For all  huge 3D printing  enthusiasts and technicians, the core focus of 3D printing is to make virtual objects tangible, flat and simple. Printing better objects closer to the virtual object is crucial to the business as a manufacturer and as a professional. Fusion deposition is s

What's the reason of China needs 3D Printing

The word “Made in China” is something we all know, whether you like it or not.  One of the reasons why China is now a vibrant economy is that Western companies have been building factories in China for the past 40 years because of low labor costs. While the new technologies such as 3D printing slowly surpass traditional manual labor at the factory, the advantage of China’s cheap labor suddenly dropped. China remains the number one manufacturing country, followed by the United States. However, noticing that new technologies enable Western companies to automate their manufacturing industries is not a national security guarantee. China’s labor costs have been rising, and the country is no longer even one of the top 10 countries in the world with the lowest labor costs. Of course, the general situation in Asian countries has improved, but does this mean that China is still successful? As Bangladesh’s average working hour is 23 cents per hour and Madagascar’s hourly wages are even below 20

The most common metal 3D printing type overview(2)

Last time, we have introduced some most common metal 3d printing type, now, i’m continue introducing it for you. Magnetic printing This system is mainly used by Vader Systems. The method uses metallic ink, sprayed and magnetized to produce very fast and complex different shapes. It is used by Lockheed Martin for aerospace. Directional energy deposition DED is actually a comprehensive term covering a large number of additive manufacturing terms. These include “Laser Engineering Net Shaping”, “Directed Light Fabrication”, “Direct Metal Deposition” and “3D Laser Cladding”. Its main purpose is to add to an existing object instead of creating a completely new one from scratch. Use laser to heat the material or wire on an existing object and weld them together using any DED method. It offers a very high ability to control the grain structure making it ideal for complex restoration work. Few materials are available in the DED compared to other methods, which may put it at a disadvant
